Evaluación por imagen en la detección del carcinoma lobulillar invasor de mama: comparación de la mamografía y el ultrasonido
2012
). Results: The analysis included 654 patients who underwent biopsy. Among them, 148 (22.62%) were positive and 506 (77.37%) negative for cancer. The average age was 48 years (range 18-89). The sensitivity of ultrasound was higher in the group of invasive lobular cancer (ILC) in 14/14 (100%) cases, in contrast to 87/111 (78%) cases of invasive ductal carcinoma (IDC) and 9/18 (50 %) cases of ductal carci- noma in situ (DCIS). The mammography showed greater sensitivity in the group of DCIS in 17/18 (94%) cases, unlike 9/14 (64%) cases of ILC and 89/111 (80%) cases of IDC. Conclusions: Ultrasound improves the detection of ILC with sensitivity up to 100% compared to 64% by mammography. The combination of both diagnostic tests showed sensitivity equal to the ultrasound, but it decreased 30% the specificity in this group.
